One thing I would say when doing them, fit longer and reroute them away from being directly over the manifold, just a belts and braces approach.

I'm intending to have them replaced soon. Nylon replacements I think my mechanic mate said, sure he said £500 all in parts and labour to replace them. Is that reasonable? Stuart hi Stuart ,…i’ve just completed full flow and return fuel lines right from tank to engine with latest new age fuel rubber out from Germany,…which apparently is one time fitment just come over but is expensive ,…but think it cost me under around £230 plus i ordered 6 meters of over sleeve fire resistant silicone covered fibreglass sleeping which was a further £100 and did it myself obviously so it’s not too bad a price if you ask me given the labour time involved ect ,…but if you need any info let me know … i was installing nylon lines when i visited this place and they told me that there’s something in fuel if it sits over time unused that will rot nylon and mentioned methanol but my brain shut off at that point and said i’ll take that if you got enough of both sizes and connectors ect. being that it’s a new age of anti corroding rubber fuel line ,… i was able to run it as i said from engine right back up the fuel tank so it’s all new along with new porsche fuel filter lines purchased last year.…. i liked it tuber as i could bend it where ever i wanted. i also made a custom plate from 3mm aluminium that bolts under car to protect the new pipes cos i’m anal like that . current porsches : 1987 944 Turbo ( modified) 1986 944 Lux (my very first car at 17 years old) last of the 986 S 3.2 speacial edition Quote Reply #262

If the hard lines themselves are fine then a kit like this is all that’s needed: https://944store.com/product/944-951-braided-black-fuel-line-kit/ Although personally, you can put that together yourself for less and without the import duty and shipping fees from the states. Obviously my attitude and experience to/of building AN lines might be different to yours. Off the top off my head you’ll need an 8mm and a 10mm compression fitting to AN adaptor, some AN6 hose and ends and an AN6-M??? (I think it’s M16 x 1.5) adaptor for the damper end. As PSH says, I’d also run them longer and flip the FPR so they come round the back of the engine bay rather than over the exhaust manifolds too. post edited by Eldavo - 2023/04/02 13:29:36 Attached Image(s) Joint 944 Register Secretary, 944 Forum Moderator Current: 1988 944 Turbo S (now 3.0 16v turbo 400bhp+) 2022 Tesla Model 3 Long Range 1966 Triumph Tiger 90 Past: 2002 996 3.6 C2 2006 987 Boxster 2.7 1988 944 2.7 Quote Reply #263

Engine splendid, oil still lovely and golden and not a drop missing. Not a drop of water gone missing. Taps have been fully opened a few times and the car is quicker than it ever was pre-rebuild. Obviously we done a few upgrades during the build but not any "add BHP" as such upgrades. I imagine the engine is just better and more efficient than it ever was before. Happy days! Since last updates (as seen on other threads) I've fixed my recirc/defrost button issue and also my temp gauge issue, as well as painted my rear wiper arm and fitted some nice new wheel centres. Next exciting update will be some new fir tree clips for the boot carpets. Ordered 20 in dark grey as burgundy is somewhat difficult to obtain! I might make them more burgundy before fitting with either paint or the kids trusty acrylic paint markers. For anybody wanting to know the fir tree clips are 8mm body x 17.5mm heads. About £3.50 gets you 20 delivered on ebay, in black, grey or dark grey. Not linen, or burgundy, or cobalt etc. unfortunately.

As you were at the 2,400 mile report above in terms of oil and water. The fir tree clips have been installed and look very passable in dark grey, to the point you'd likely never notice they weren't faded burgundy! Happy days!

Still need to get the fuel lines done soon. What are your thoughts on the next oil change? Changed the running in oil after about 500 miles. Now done 2,500 odd miles on proper oil. Haven't lost a drop but it is ever so slightly darkening now which is to be expected I suppose, still quite golden however. Car hasn't had a hard time. mostly leisurely miles.

I remember using some cheap, fluid-ish oil for the first start up and after the engine had done a few heat cycles and shown no issue running mostly at tick over I removed the oil, inspected it up close for possible debris and put definitive proper oil in it. Replacing the oil again at 2,500 miles would make sense to me only if you had not checked for debris before. Quote Reply #273

Had next to no debris in it at 500 miles. I'll probably wait until 5,000 miles on the proper oil then until I do the next change.

The handbook states to expect oil usage of approx 1L every 600 miles, mine will use a little oil under boost although not always, I guess it depends how high the boost goes. Driving with no boost uses nothing, or at least not that I can tell. Pete 944 Turbo......was 368BHP/382Torque.... now more... Quote Reply #277

Good luck with the rebuild Dave, mine definitely used oil before my rebuild. Probably half a litre per 1k miles or so. Mainly out the leaking sump and cam cover gaskets I hasten to add.........a distant memory now! Pete, yeah I haven't been going mad with boost, the odd burst here and there. The turbo was rebuilt a while ago and looked perfect when it was all apart. It's still an old school turbo albeit with a larger hotside if I recall correctly............
